Specification of Letters Patent.

Patented Jan. 4, 1910.

Application filed August 19, 1909. Serial No. 513,602.

To all whom it may concern:

Be it known that I, HARRY H. ADAMS, a

- citizen of the United States, residing in the c ar, but also toenlarge the passageways particularly at the entrance and exit so as tofacilitate as much as possible the rapid ingress and egress ofpassengers. -This tendency to facilitate the movement .of passengers ingetting on and ofi' cars is particularly noticeable in connection withpay-as-youenter cars, in connection with which it i's sometimesdiiicult'to maintain the desired space for passageway and doors becauseof these limitations, the' width of the door opening in cars as nowcommonly construct-f e the barriers employed for guiding passen- .gersin this type of car. '4

My present invention relates to an L iniprovement in the construction ofstreet 'railway cars with the object of obtaining the maximum width ofdoorways through the end walls of the car. As now constructed the enddoorwa s are closed by centrally divided sliding doors which openintoside recesses or pockets formed in the end walls of lthe car. Thewidth of the door opening is necessarily limited in this form of car bythe width or extent of the door receiving pockets or recesses, which areinturn limited by the presence of the main vertical corner posts of thecar body. By reason of the end walls will escape the limitations of thecorner posts. By this arrangement I am able to construct a car with anavailable doorway of approximately one half the entire free exteriorwidth between the side walls of the car, since the sliding doors forclosing the doorway are permitted to move into their pockets or recessesto the inner faces ofthe Ioutside skin or sheathing of the car. l

In order that my'invention may be fully understood, I will firstdescribe the samey with reference to the accompanying drawings andafterward point out the novelty more particularly in the annexed claims.

In said drawings Figure 1 is a diagrammatic'plan View or floor plan withthe central part broken away, of a street railway car embodying myinvention. Fig. 2 is a detail end elevation' of the same with theplatform and vestibule omitted. Fig. 3 is a-detail horizontal plan viewof a part of the same. Fig. 4t is a view similar to Fig. 3 of a slightmodification. l

Without going into immaterial details as to the general construction .ofthe street railway car to which my improvement relates, it will beobserved from the drawings that 1 is the car floor, 2 the paneled sidewalls, 3 the end walls, and 4 the end platforms around which are builtvestibule walls 5.

The side walls are built upon` the upright central doorway.15 which itis desirable to construct with as wide a free openingv as possible .tofacilitate the movement of passengers. The doorways 15 are closed by tworigid panel sliding doors 20 hung in the usual manner upon track bars 21and 22, extending above the door opening and to the sides thereof. Thesesliding doors 20 meet, when closed, in the central vertical longitudinalplane of car, and rest, when opened, in pockets or recesses 25 formedbetween the panels of the end walls 3 upon opposite sides of the dooropening 15. As stated above the extent of these door receiving pocketsor recesses is usually limited by the presence of the corner posts atthe four corners of the car body. f In my im roved construction, asshown particularly 1n Fig. 3, I have formed each corner post of twostuds lOand 10a separated as shown and rigidly braced together byV steelplates 30 and 31 and by the other parts ilo of the car which are builtupon the corner post studs. ner post `is arranged flush with the innerpanel of tlieend wall, while the auxiliary stud section 10a is arrangedflush with the outer panel of Said end wall, so that each door receivingpocket or recess 25 will 'extend to the outer skin or sheathing of thecar between corner studs 10, 10a, thereby giving the door receivingpockets or recesses the greatest possible width so as to receive agreater width of door and permit the use of a wider doorway or opening.

In Fig. 4: theauxiliary part l0a of the corner post is in the form of ametal bracket or plate 35, and the door 20 is hung to slide upon theouter face of the end wall of the car, the usual front anel of the endwall being omitted, if pre erred.

What I claim is:

1. In a car construction, 'the combination with a car body having acentrally arranged doorway in its end wall of approximately one Ahalfthe entire free width of the exterior of the car, separated studsforming divided vertical corner posts or supports, door receivin pocketsin the end wall of the car upon bot 'sides of said. doorway, said Themain stud l0 of each cor-- pockets extending between said separatedstuds to the side walls of the car, and centrally separating rigidsliding doors mounted in said door receiving pockets and adapted, whenopen, to aord a free passageway of substantially the entire Width of thedoorway. 2. In a car construction, the combination of the car bodyhaving a floor, side walls and end walls, each of the end walls beingprovided with a central doorway of approximately one half thefentirefree`width of the exterior of thelca'r, vertical corner`posts atv HARRYH.
